Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

The study concerns the unloading of pigs at the slaughter house, both from the pigs view and from the transporters view. The study has been carried out at the slaughter house (SLP) in Helsingborg, Sweden. It includes a questionnaire to all transporters (65 % response) and a direct observation of the unloading. The transporters handling of the pigs, their use of different equipment and the response of the pigs has been studied. The pigs behaviour at unloading and their reactions to environmental factors has also been studied.

The aim of this study is to examine how preschools contribute to the forming of identity in children, with a specific focus on the quiet and socially withdrawn child. How do the teachers describe the quiet child and the socially withdrawn child? Are there any opportunities for children to be quiet/withdrawn in preschools? These questions have also been analysed from a gender perspective. The method chosen is qualitative method. Nine preschool teachers from two Swedish preschools have been interviewed.

Nuclear power plants existences have been well debated since the 70s (Swedish radiation safety authority, 2014). Accidents, risk and presence connected to nuclear power plants have been part of many studies around the world. Recent studies have shown a connection between prices of houses and the distance and presence of nuclear power plant in a surronding area of the house. This paper uses Hedonic price modelling to investigate the willingness to pay for an increased distance to the Swedish nuclear power plant, Forsmark. For the dependent variable selling price was used and the independent variables were number of rooms, living area, other area, lot size, selling year, building year and distance to Forsmark.

Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.

The purpose of this thesis is to investigate if there is a risk that Sweden will go in to crises at the house market and in the bank sector. The Swedish house prices have in the last years growth very high and quickly and are now over the development in the beginning of 1990. The method I use to investigate this is a multiple regression model. I follow a regression that both OECD and the Swedish Riksbank use. The difference between my analyse and theirs is that we use different periods..

This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

This degree project is an inquiry in how plan layouts and functions should be designed to suit families with children. The project aim to, if possible, find good solutions and designed houses that satisfy the requirements a family have.Last spring we contacted Willa Nordic AB, a company that produce houses, and they had a suggestion to investigate living for families with children. Their motif were that they lacked in information and knowledge in how to design houses that correspond to a family's needs. We thought the idea was exiting and motivating.The autumn 2008 studies were made on earlier published reports, in the subject "living environment", to get a solid background. The earlier inquiries shows a clear development through the whole 1900's, from being without standards to have well defined norms.

Intro: 80 percent of the Swedish population own shares. This makes Sweden the leading country in private investment in securities. It can be difficult for the private investor to know where, when and which security to invest in. The strategies are as ambivalent as the stock markets fluctuations. If the investor prefers to refrain from investing money himself, there are brokers who carry out these types of services.

AbstractDuring the last five years there has been a considerable immigration from the Netherlands to Värmland in Sweden. INVA, Invest in Värmland, wanted to highlight this phenomenon and therefore contacted Karlstad University to make a survey about how extensive the immigration is and what consequences it brings for the business life and municipalities in Värmland. We were luckily chosen to perform this research and the main focus in this study has been the following questions:? Why do the Dutchmen choose to buy their house in Värmland?? What are the main reasons for leaving the Netherlands?? What consequences does the immigration cause for the business life in Värmland?? How do the Dutchmen experience the contact with Swedish authorities?To answer the questions we designed a questionnaire that was sent to 200 Dutch house purchasers. The ambition was to survey all the Dutch house purchasers in Värmland, but with the time constrains and the municipalities having problem to find complete data, we limited the survey to 200 households.

The purpose of the study is to examine, describe and analyse how a selection of parents to children with Asperger syndrome understand, experience and cope with their parenthood. To attain this purpose we focused on these following questions;How does the respondents view their parenthood?; What kind of strategies does the respondents use to cope with their parenthood on the basis on their child with Asperger syndrome?; How does the respondents experience the mesosystem interact with them regarding situations contenting strenuous and stress?We chose to do a qualitative study by conducting separate interviews with eight parents to children with Asperger syndrome. Then we analyzed the answers using an abductive research, we tested the empirical data against our choice of theoretical perspectives. The results shows; that several of the parents in the study have experiences of high strenuous and stress in combination the several roles their parenthood contained.

Urbanization and the flight of the creative class drains the countryside when it comes to creativity and talent. Especially the young leave sleepy societies. Richard Florida claims that the city attracts the creative class and enables for economic growth to flourish. Robert Putnam adds to the picture by saying social capital might be equally effective as nourishment for growth. In Uddebo, a rural village in the south of Sweden one combines the two creating a vivid society where creativity flies high and ideas fertilize each other?s.

Background: Risk Management plays an important part of the enterprises strategic business activity. Efficient Risk Management will secure the businesses survival, assets and creates market advantages. The interest of information security has consequently gained in Swedish corporations. Corporations have realized the importance of the information which is stored in the IT systems. IT is the tool for businesses future progress and growth and therefore a source of risks.
